I see this on our system as well...where maybe 5 or 6 machines replicate themselves. In the Inventory, when I look more closely the machines in question will have two different values for Serial Number. One looks plausible, while the other is the Machine Name. Kind of odd. I delete the ones with the MachName and they go away for a while.

Thanks bytesnake. Those are actually my settings. I'm guessing it's something else. If it were dozens of boxes, then I'd be more worried. The fact that they stay away after deletion says it might be some other reason, maybe a scan getting interrupted and repeating or something equally simple.

Only way I know of getting rid of the dupes is to knock them out one by one. But for me I am glad I looked behind the scenes so I could see which one was the more likely "bad" record.

There have been a number of Feature Requests for Spiceworks to better deal with multi-homed devices.

Visit the Feature Requests and have a look through the requests and/or search for requests about Multi-homed or duplicate devices, then any you like the sound of Spice em up to enhance the likelihood of seeing them in a future version of Spiceworks.
